DETAGHABLE HEEL.

Specification of Letters Patent.

Patented Apr. 18, 1911.

Application filed August 18, 1910. Serial No. 577,765.

To all whom it may concern:

Be it known that I, J osnrn l/Vrnnsnbrnn, a citizen of Germany, residingat Herzegstrasse 102, Dusseldorf, in the Province of Rhineland andKingdom of Prussia, Germany, have .invented new and useful Improvementsin Detachable Heels, of which the following is a specification.

The present invention contemplates a de tachable heel in which a disk,used as a heel-piece, is adjustably attached below the heel-body. Whenworn away at one part of its under surface, such disk is moved byturning or displacing it with another part to that side of the heel,which is more particularly subjected to wear and tear.

The essential feature of the invention lies in the fact, that the diskand the heel have at their lower part the form of an equilateraltriangle having curved sides and rounded angles; thus the heel-piece orthe disk, after being turned through 120 in one or the other direction,always coincides with the heel. So the arrangement allows of displacingtwo times or of using the disk-or the heel-tap in three positions,without it being necessary that both parts differ remarkably from theform of the heel generally in use.

The accompanying drawing, in which similar letters referto similar partsthroughout the several views, shows the new arrangement in one form ofembodiment.

The Figure 1 is illustrative of the heel in elevation. The Fig. 2 showsthe heel likewies in elevation, but with disk removed and placed aside.Fig. 3 is an upper plan view and Fig. 1 a longitudinal section throughthe heel.

The heel a is shaped, at least at its lower part, in the form of anequilateral triangle having curved sides and rounded angles. The bottomof the heel has fastened thereto a triangular plate 6, made preferablyof metal. This is fitted with a tapped aperture 0. The disk or theheel-piece d to be fastened to the heel has exactly the form and size ofthe lower heel-parts. It carries at top a recess 6 corresponding in sizeand shape to the plate 6 and arranged in such a way that the disk (Zwhen pushed therewith over the plate 7) perfectly coincides with theheel. By this arrangement the disk (Z is kept from turning withoutfurther trouble. The disk can be fixed, as shown, by means of a screw fto be screwed into the tapped opening 0 of the plate Z) which with itshead bears against a thin metallic plate 5/ adapted at or in the disk(Z. This plate g may carry, as shown, upwardly directed lugs preferablyformed by the punching process, with which it engages the recess 6 andembraces the sidewalls of plate Z). l/Vhen disk (Z is worn along one ofits sides, screw f is slackened, the disk is lifted off plate Z), andafter being turned through an angle of 120 is re-attached. Thisoperation may be repeated when the second side of the disk has becomeworn, so that all three sides of the disk may be consecutively utilizedfor standing the maximum wear.

The disk (Z may be made of one or several layers of leather or of rubberor of any other suitable material.

I claim 1. A device of the character described, comprising a heel, thelower portion of which is of equilateral triangular shape with roundedangles, a disk of like shape and size, and means for adjustably securingthe disk to said lower heel portion.

2. A device of the character described, comprising an equilateraltriangular heel having curved sides and rounded angles, a disk of likeshape, and means for adjustably securing the disk to the heel.

3. A device of the character described, comprising a heel, a triangularbottom plate secured thereto, an equilateral triangular disk havingcurved sides and rounded angles, and recessed to receive the bottomplate, and means for adjustably securing the disk to the heel.
